Valve System Test Centre

Product information

With this unique product it is very easy to test a valve system. It can be used for the following systems:

Modulating and on/off systems

Hydraulic and pneumatic

Rotary and linear

Double acting and spring return

Because of the compact and mobile design the VSTC can be used in the workshop or on inspections in the field.The VSTC makes automatic tests of the valve system and stores all valve system data on a pc, with the software included in the kit. With these data it is easy to generate reports showing information and graphs of the valve system performance.

Software

The Valve System Test Centre software is designed to automate the test and give an easy overview of the testresult.

The following tests can be performed:

Stroke test

System test

Step test

Life cycle test

Deadband test

Pressure test

Pressure switch test

Flushing sequence

Licence and updates

1 licences is delivered with every VSTC unit. Licence includes the following:

Support by phone and e-mail for 1 year

Free upgrade 1 year

It is possible to expand the support and upgrade.

Enclosure types

All modules are available in two enclosure types.

19" 2U rack modules

This enclosure is designed to be mounted in a 19" rack.

Desktop Stackable modules

This enclosure is stackable and designed to be placed directly on the desktop.
